Class RestResponse<T>

  • All Implemented Interfaces:
    AutoCloseable
    Direct Known Subclasses:
    RestResponseImpl
    public abstract class RestResponse<T>
extends Object
implements AutoCloseable
    Defines the contract between a returned instance and the runtime when an application needs to provide meta-data to the runtime.

    An application class should not extend this class directly. RestResponse class is reserved for an extension by API implementation providers. An application should use one of the static methods to create a RestResponse instance using a RestResponseBuilder.

    Several methods have parameters of type URI, UriBuilder provides convenient methods to create such values as does URI.create(java.lang.String).

      • getEntity

        public abstract T getEntity()
        Get the message entity Java instance. Returns null if the message does not contain an entity body.

        If the entity is represented by an un-consumed input stream the method will return the input stream.

        Returns:
        the message entity or null if message does not contain an entity body (i.e. when hasEntity() returns false).
        Throws:
        IllegalStateException - if the entity was previously fully consumed as an input stream, or if the response has been closed.

      • readEntity

        public abstract <OtherT> OtherT readEntity​(Class<OtherT> entityType)
        Read the message entity input stream as an instance of specified Java type using a MessageBodyReader that supports mapping the message entity stream onto the requested type.

        Method throws an ProcessingException if the content of the message cannot be mapped to an entity of the requested type and IllegalStateException in case the entity is not backed by an input stream or if the original entity input stream has already been consumed without buffering the entity data prior consuming.

        A message instance returned from this method will be cached for subsequent retrievals via getEntity(). Unless the supplied entity type is an input stream, this method automatically closes the an unconsumed original response entity data stream if open. In case the entity data has been buffered, the buffer will be reset prior consuming the buffered data to enable subsequent invocations of readEntity(...) methods on this response.

        Type Parameters:
        OtherT - entity instance Java type.
        Parameters:
        entityType - the type of entity.
        Returns:
        the message entity; for a zero-length response entities returns a corresponding Java object that represents zero-length data. In case no zero-length representation is defined for the Java type, a ProcessingException wrapping the underlying NoContentException is thrown.
        Throws:
        javax.ws.rs.ProcessingException - if the content of the message cannot be mapped to an entity of the requested type.
        IllegalStateException - if the entity is not backed by an input stream, the response has been closed already, or if the entity input stream has been fully consumed already and has not been buffered prior consuming.

      • hasEntity

        public abstract boolean hasEntity()
        Check if there is an entity available in the response. The method returns true if the entity is present, returns false otherwise.

        Note that the method may return true also for response messages with a zero-length content, in case the "Content-Length" and "Content-Type" headers are specified in the message. In such case, an attempt to read the entity using one of the readEntity(...) methods will return a corresponding instance representing a zero-length entity for a given Java type or produce a ProcessingException in case no such instance is available for the Java type.

        Returns:
        true if there is an entity present in the message, false otherwise.
        Throws:
        IllegalStateException - in case the response has been closed.

      • bufferEntity

        public abstract boolean bufferEntity()
        Buffer the message entity data.

        In case the message entity is backed by an unconsumed entity input stream, all the bytes of the original entity input stream are read and stored in a local buffer. The original entity input stream is consumed and automatically closed as part of the operation and the method returns true.

        In case the response entity instance is not backed by an unconsumed input stream an invocation of bufferEntity method is ignored and the method returns false.

        This operation is idempotent, i.e. it can be invoked multiple times with the same effect which also means that calling the bufferEntity() method on an already buffered (and thus closed) message instance is legal and has no further effect. Also, the result returned by the bufferEntity() method is consistent across all invocations of the method on the same RestResponse instance.

        Buffering the message entity data allows for multiple invocations of readEntity(...) methods on the response instance. Note however, that once the response instance itself is closed, the implementations are expected to release the buffered message entity data too. Therefore any subsequent attempts to read a message entity stream on such closed response will result in an IllegalStateException being thrown.

        Returns:
        true if the message entity input stream was available and was buffered successfully, returns false if the entity stream was not available.
        Throws:
        javax.ws.rs.ProcessingException - if there was an error while buffering the entity input stream.
        IllegalStateException - in case the response has been closed.

      • close

        public abstract void close()
        Close the underlying message entity input stream (if available and open) as well as releases any other resources associated with the response (e.g. buffered message entity data).

        This operation is idempotent, i.e. it can be invoked multiple times with the same effect which also means that calling the close() method on an already closed message instance is legal and has no further effect.

        The close() method should be invoked on all instances that contain an un-consumed entity input stream to ensure the resources associated with the instance are properly cleaned-up and prevent potential memory leaks. This is typical for client-side scenarios where application layer code processes only the response headers and ignores the response entity.

        Any attempts to manipulate (read, get, buffer) a message entity on a closed response will result in an IllegalStateException being thrown.

        Specified by:
        close in interface AutoCloseable
        Throws:
        javax.ws.rs.ProcessingException - if there is an error closing the response.

      • getLanguage

        public abstract Locale getLanguage()
        Get the language of the message entity.
        Returns:
        the language of the entity or null if not specified.

        The returned builder has its own response headers but the header values are shared with the original RestResponse instance. The original response entity instance reference is set in the new response builder.

        Note that if the entity is backed by an un-consumed input stream, the reference to the stream is copied. In such case make sure to buffer the entity stream of the original response instance before passing it to this method.

        Parameters:
        response - a RestResponse from which the status code, entity and response headers will be copied.
        Returns:
        a new response builder.
